Coinbase's Layer-2 blockchain, Base, has been making waves in the Ethereum scaling space, and recent data show that its ambitious goal of reaching $5 billion in total value locked (TVL) is not just hype, but a tangible reality fueled by a thriving developer community. As of September 2025, Base boasts near $12 billion TVL, more than 1.5 times that of one of its main competitors, Arbitrum, which sits at about $7.4 billion. What’s driving this impressive growth? A combination of real user engagement, low transaction fees, and over 25,000 developers building on the platform—all backed by Coinbase's strong ecosystem.
